"N" - Dangerous for the environment R52/53 - Harmful to aquatic organisms, may cause long-term adverse effects in the aquatic environment. EMERGENCY OVERVIEW IMMEDIATE CONCERNS: Flammable liquid and vapor. Vapors and/or aerosols which may be formed at elevated temperatures may be irritating to eyes and respiratory tract. POTENTIAL HEALTH EFFECTS EYES: Severely irritating. If not removed promptly, will injure eye tissue, which may result in permanent damage. SKIN: Prolonged or repeated contact may cause skin irritation. INGESTION: This product is toxic by ingestion. Ingestion may cause irritation of the digestive tract. Nausea and vomiting will most likely occur. INHALATION: Prolonged or repeated inhalation may cause lung damage and/or central nervous system disturbances. SIGNS AND SYMPTOMS OF OVEREXPOSURE EYES: Symptoms of overexposure include: stinging, tearing, redness and pain. SKIN: Prolonged exposure causes redness, pain, drying and cracking of the skin.

2 Page 2 of 9 INGESTION: Swallowing of this material may result in nausea, vomiting and weakness followed by central nervous system depression. INHALATION: High concentrations may lead to central nervous system effects (drowsiness, dizziness, nausea, headaches, paralysis and loss of consciousness). ACUTE TOXICITY: Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result. CHRONIC EFFECTS: CNS depression, dermatitis, reproductive hazard. ROUTES OF ENTRY: Inhalation is major route of entry. TARGET ORGAN STATEMENT: Prolonged or repeated overexposure may cause central nervous system, kidney, liver, and lung damage. SENSITIZATION: Possible cardiac sensitization. 3. COMPOSITION / INFORMATION ON INGREDIENTS Chemical Name Wt.% CAS EINECS Benzene- methyl, (Toluene) Xylenes (o-,m-,p- isomers) Polysiloxane mixture FIRST AID MEASURES EYES: Immediately flush eyes with plenty of water for at least 15 minutes. Get immediate medical attention. SKIN: Immediately flush with large amounts of water. Use soap if available. Remove contaminated clothing, including shoes, after flushing has begun. Get prompt medical attention. INGESTION: Aspiration hazard. If swallowed, vomiting may occur spontaneously, but do not induce. If vomiting occurs, keep head below hips to prevent aspiration into lungs. Call a physician immediately. INHALATION: Remove to fresh air. If not breathing, give artificial respiration or give oxygen by trained personnel. Seek immediate medical attention. 5. FIRE FIGHTING MEASURES FLASHPOINT AND METHOD: (40 F) TAG CC FLAMMABLE LIMITS: Not Established to Not Established GENERAL HAZARD: Flammable Liquid. Can release vapors that form explosive mixtures at temperatures at or above the flash point. EXTINGUISHING MEDIA: Water, foam, dry chemical, carbon dioxide.

3 Page 3 of 9 HAZARDOUS COMBUSTION PRODUCTS: Smoke, fumes and oxides of carbon. EXPLOSION HAZARDS: Vapors may form explosive mixture with air. FIRE FIGHTING PROCEDURES: Use water spray to keep fire-exposed containers cool and to knock down vapors which may result from product decomposition. FIRE FIGHTING EQUIPMENT: As in any fire, wear self-contained breathing apparatus pressuredemand, (MSHA/NIOSH approved or equivalent) and full protective gear. 6. ACCIDENTAL RELEASE MEASURES SMALL SPILL: Dike area to contain spill. Take precautions as necessary to prevent contamination of ground and surface waters. Recover spilled material on adsorbent, such as sawdust or vermiculite, and sweep into closed containers for disposal. After all visible traces, including ignitible vapors, have been removed thoroughly wet vacuum the area. Do not flush to sewer. If area of spill is porous, remove as much contaminated earth and gravel, etc. as necessary and place in closed containers for disposal. ENVIRONMENTAL PRECAUTIONS WATER SPILL: NEVER FLUSH TO SEWER. GENERAL PROCEDURES: Absorb the liquid and scrub the area with detergent and water. 7. HANDLING AND STORAGE HANDLING: Empty containers will retain product residue and vapor and should be handled as if they were full. STORAGE: Store in a cool place in original container and protect from sunlight. STORAGE TEMPERATURE: Store in a cool place below ( 120 ) F (49 ) C. STORAGE PRESSURE: Store at local atomspheric pressure. 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
